A manufacturer of merry-go-rounds uses 8 identical wooden horses, 4 identical plastic motorbikes and 2 different miniature car. They are all equally connected around the rim of a circular moving base. Establish how many different arrangements there can be if the 2 cars are not to be placed in consecutive positions.
I don't understand how to work it out if you don't want the 2 cars to be next to each other.
Any help would be much appreciated.
